Nawr, mae'n ddiddorol nodi y gall traciau trên fod 20 gradd Celsius yn boethach na thymheredd yr aer pan fydd gwres eithafol, a dim ond ar ôl iddynt gyrraedd tymheredd o 24 gradd Celsius y gallwch atgyweirio traciau trên.

Now, it's interesting to note that train tracks can be 20 degrees Celsius hotter than air temperature when there's extreme heat, and you can only repair train tracks once they reach a temperature of 24 degrees Celsius.

Er enghraifft, yn Abertawe, pan newidiwyd y trên olaf ar gyfer rhai llwybrau o 9.30 p.m. i 11.00 p.m., gwnaeth wahaniaeth enfawr i leoliadau cerddoriaeth yn y ddinas.

For example, in Swansea, when the last train for certain routes was changed from 9.30 p.m. to 11.00 p.m., it made a vast difference to the music venues in the city.
